So every M3 except the E9X m3 is a complete fail?
If you didn't know the E9X m3 was the only M3 to have a "unique M division R&D" engine. Which really was really a variant of the only "true M" engine the S85(v10 in last M5. All other M3's had a modified/upgraded/variant of a standard
E46 M3: S54 engine based on M54 engine in 330's
E36 M3: S50 engine based on M50 engine found in 325's
E30 M3: S14 engine based on M10 and M88 engines found in lots of older Bmw's
